Develop Together -5 (Add DBSet<>)

Enter the Business layer and open the Class named SaleContext in the Context folder and add the entity name of the new module you will add to the bottom.
For example, public DbSet<(ModulName)> (ModulName) { get; set; }. Enter the OnModelCreating code blogs directly underneath it, and again, at the bottom, add modelBuilder.Configurations.Add(new (ModulName)Mapping()); codes.
Then there is not much left to do. Let’s focus on our form.
